Improvement in gang-plows



PATENT rtree@ OVATVVOOD, OF LEBANON, ILLINOIS.

IMPROVEMENT IN GANG-FLOWS.

Specification forming part of Letters Patent No. 54,089, dated April 24,1866.

To all whom it may concer/n:

Be it known that I, OARRELL ATWooD, of Lebanon, in the county of St.Clair and State of Illinois, have invented a new and useful Improvementin Gang-Flows; and I do hereby declare that the following is a full andclear description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Figure 1 of the accompanying drawings is a plan of one of the improvedplows. Fig. 2 is a rear-end elevation of the same. Fig. 3 is a sectionalelevationl taken on the line a b in Figs. l and 2. l

This invention relates, first, to the connection between the `forwardend of the supporting-frame and the plow-beams; secondly, to theadjustable connection between the metallic head plate on the front ofsupportingframe and the ends of the aXle, whereby the whole machine maybe adjusted to a correct alignment; thirdly, to a combination of leversand brakes for the purpose of keeping the plows in the ground while atwork; fourthly, to the adjustable clamp on the rear ends of theplow-beams for the purpose of adjusting the plows by means of a movablebrace, so as to throw the points of the plows more or less down.

To enable those skilled in the art to make and use my gang-plows, I willproceed to describe their construction and operation.

The axle A, the wheels A', (not shown in model,) and thesupporting-frame A2 are of the usual construction in common use, andconsequently will not be minutely described here.

The guiding-frame for the plow-beams, composed of the metallic stands BB and the beam B', the adj ustability of these parts to differentwidths, and their connection with the axle are the same in detail as thesimilar parts in a patent already allowed to myself. Consequently theywill not be described here or alluded to any further than they areconnected with the parts especially incorporated in the presentinvention.

C is a metal plate, placed on top of the forward ends of the beams ofthe frame A2 and fastened to them by means of the bolt a andbeam-sockets a2. Slots a are made in the plate C for the passage of thefastening devices a and a2, which, after passing through the plate C andframe A2, are secured in position by meahs of the nuts a3 on the bottomof the frame A2. By loosening these nuts the slot a will admit of anydesired regulation ot' the width of the frame, after which it may beagain iirmly secured by tightening up the nuts a3.

On either sideof the machine there is a brace or tiered, D, the forwardend ot' which is firmly secured to the plate C, while its back endpassesv through an eyebolt or other similar device attached to the axle,and is there secured by the nut b.

After the machine has been set up it may be correctly aligned byloosening one of the nuts b and tightening the other, and vice versa.

A shaft, E, has its bearings in the lower ends ot' the -stands B,between which points of support it is provided with a short lever, E',the outer end of which is arranged to hook onto a series of hooks on thelower end of the hook-rod F, which is suspended under the cross-bar Gr,to which it is securely attached by means of connecting-links. n

The bar G rests on top of the plow-beams H. rI he drivers seat (notshown) should be located on the outer end of the beam B' at s, fromwhich position he can easily place his foot on the lever E2, the lowerend of which is irmly attached to the shaft E. By pressing down thelever E2 the driver can transmit, through the medium oi' the shaft E,lever E', and rod F, any required amount of pressure to the bar G, andthus hold the beams H down, so as to keep the plows H in the ground.

These devices are intended to overcome a difculty experienced by farmersin keeping the plows in the ground in some kinds of soil, especiallyhard or stony ground.

The plow-post H2 is fastened to its beam by a single bolt, d, so thatthe lower end of it may swing backward or forward, as may be required toaccommodate the length of the brace H3, which is fastened to the post bymeans of the bolt d', which admits a like lonA gitudinal motion. Theupper end of the brace H3 passes through a strap-piece, c, attached tothe rear end of the beam H, and is then se cured by means ot' thesetscrew c. The brace H may be adjust-ed so as to place the plow more orless forward, thereby throwing the point of it more or less elevated,and then the parts thus adjusted secured in position .by

tightening the set-screw c'.

Having described my invention, vWhat I vclaim is- 3. The combination ofthe shaft E, levers Eand E2,`hookr0d F, and cross-bar Gr, or theirequivalent devices, with the plow-beams of gang-plows, for the purposeherein set forth.

4L. The combination of the strap-piece c and set-screw c with the beam Hand with the braces H3, as and yfor the `purpose set forth.
